Other objects and advantages of the invention will appear as the description of the drawings proceeds. However, I desire to have it distinctly understood that I do not intend to limit myself to the exact details shown or vdescribed but that I'intend to vinclude as part of my invention all such obvious changes and modifications of parts as would occurto a person skilled in' this art claims.

In-the drawings: 1

Fio'. 1" s' a sideelevation of my improved switc ilmechanism and lamp socket member with the outer insulating tubular member in section Fig. 2. is a similarview taken at right angles to Fig. 1;'

Fig. 3 isa section taken on the-line 3-3 v ofF1g.1;

Fig. 4 is a section taken on the line 4-4 of Fig. 15

Fig. 5 1s a the line 5-5 of Fig. 1; and .Fig 6 is a section taken on the line 6- of F 1 2. Referring in detail to the drawings, my improved switch mechanism comprises a fragmentary section "taken on l switch frame 10 upon which is mounted a movable contact arm 11, said. arm being pivoted on the insulating pivot members 12 and being operated by suitable actuating mechanism, such as that shown in the patent to Gordon, No. 1,473,224, patented November 6, 1923, the details ot this mechanism not being a part of this invention. For the purposes of this invention, it suilices to say that the actuating mechanism comprises a spring 13 which produces a snap action of the movements of the movable switch arm 11 and also serves to retract or move inwardly the projecting actuating member 14.

A pair of flat sheet insulating members 15 are carried by the switch trame 10, said switch frame having paired lugs 16 extending through paired openings 17 in the members 15 to properly position the members 15 relative to the frame l0, said members being furthermore secured together at the lower ends thereof by means of at least one transversely extending securing and spacing member 18 which is provided with paired projections 19 extending through suitable openings inthe members 15 and clinchedover so as to secure said members firmly together at theirl lower ends. A linger 20 and a pair of fingers 21 are provided on the member 18 projecting outwardly therefrom, the member 20 projecting into a suitable opening 22 in the tubular insulating covering 23 and the members 21 serving as stop flanges for limiting the downward movement of the member 23 on the combined switch and lamp socket device.

At their upper ends, the members 15 are secured together and held in properly spaced relationship by means of the conducting cross members 24 and 25 which are provided with the paired projections 26 that are upset so as to secure the members 15 together and properly space the same and also prevent twisting of the members 1 5. Due to the provision of the paired proJections 16,-

the member 18 and the members 24 and 25 connecting the members 15 together, a very substantial and rigid box-like frame-work made up of said members is provided.

The members 24 and 25 have the contact members 27 and 28 provided thereon which are adapted to be bridged by the contact 11 as shown in Fig. 6. The contacts 27 and 28 may be of any desired form, but are shown as converging from the members 24 and 25 toward the free ends thereof and terminating in convex contact making portions 29. The ends thereof that are secured to the members 24 and 25 are turned substantially at right angles to the conver ing portions thereof and are made somew iat wider as indicated at 30 so as to provide for suiiicient material for the rivets 31 by means of which the same are secured to the members 24 and 25. The member 24 is also provided with a' binding screw 32 which serves as one of the wiring terminals of the device and the member 25 is provided with an upwardly extending ear 33 upon which is mounted the center contact 34 of the lamp socket.

The lamp socket is provided with a screw shell 35 as is customary and said screw shell is provided with an inturned lip or flange 36 that is arcuate in shape and is provided with a break therein at 45. Engaging said flange 36 is a holding member having an arcuate body portion 37 overlying the flange 36 and provided with depending apertured ears 38 and 39 which have screw-threaded openings for receiving the screw-threaded securing member or bolt 40. A. depending apertured ear 41 is also provided on the screw shell 35 which lies between the head 42 of the screw or bolt 40 and the ear 39. The screw or bolt 40 also passes through suitable openings in the members 15 and it will be seen thatI when the member 40 has passed through the various openings, the same will hold the screw shell firmly in positionl on the insulating members 15. In order to positively hold the screw shell from rotation relative to the insulating members 15,` the flange 36 is widened at a plurality of points indicated by the numeral 43 and cut away between said thickened portions so as to provide pairs of shoulders 44 between which the down-turned ears 38 and 39 lie, the holding member 37 and the screw shell 35 thus being interlocked so that the screw shell will not rotate relative to the holding member.

An insulating gasket or washer 46 is mounted between the end of the shell 35 and the ends of the members 15 and is provided with an opening 47 in the form of a slot through which the ear 38 projects and with a notch 48 through which the ears 39 and 41 project. 4The washer 46 is further provided with an opening 49 for the extension 33 of the member 28 so that the same may be passed therethrough and the center contact 34 placed in the pro er position in the socket. It will be seen t at the washer or gasket 46 is held firmly in position between the screw shell 35 and the members 15 when thev fastening member 40 is put in place. Upwardly extending ears or tongues 50 are provided on the members 15 seating in the notch 48 and the slot 47 to furthermore hold the parts in proper relationship to each other.

The screw 40 acts as a wiring terminal screw, the end of a conductor being insert able below the head 42 of the screw and between the same and the ear 41, the same being clamped in position by means of the screw. 1n order to insulate any strands of the conductor that might accidentally come in engagement with the rojeetions 26, 9. layer of insulating material 51 is inserted between the ear 39 and the member 15, having an opening 52 therein through which the screw 40 passes.

Secured to the switch frame 10 is a bracket 53, the upper transversely extending portion 54 of said. bracket being secured tothe member 10 in any desired manner and having an 'opening 55 therein through which the actuating member 14 extends. The bracket isprovided with an offset at 75 and with a lower end portion 56 extending transversely to the main body portion of the bracket. An internally threaded sleeve 57 is secured thereto in any desired manner.

The vertically extending portion of the bracket 53 is provided with a pair of closely spaced openings 58 which4 are separated by means of the web 59. VAn oblong opening 60 is provided in the member 14 and the lever 61 extends through said opening 60 having a notch 62 therein for positioning the member 14 relative thereto. One end of the lever 61 is provided with a pair of hooklike fingers or bifurcations 63 which are bent around the web 5.9 extending through the openings 58, thus pivoting the lever 61 j on the web 59, the web 59 acting' as a fulcrum for the lever. Fig. 2, the lever is made of two pieces of sheet metal which lie face to face and are secured together by means of the rivet 64. The end of the lever 61 opposite the bifurcated end thereof, is flanged outwardly from the center thereof as indicated at 65 and has a pair of parallel flanges 66 thereon formin a channeled guide for the pull chain 6 said pull chain being mounted in the end flange 68 provided in said channeled portion of the lever. The upper edge of the lever is provided with an outward projection 69 which isy adapted to engage against the transversely extending upper Vend 54 of the bracket 53 to limit the upward movement of the lever 61 due to the retractile effort of theA spring. 13. A notch 70 is provided in the member 23 to provide clearance for the lever 61 so that the same willnot strike against the tubel 23, but against the met-allie member 54.'

Obviously, the screw-threaded sleeve 57 is threaded onto a screw-threaded nipple or other means for mounting t-he socket and switch mechanism in position. The bracket 53 mounted thereon in turn supports the supporting member or switch frame 10 which carries the insulators 15, which insulators in turn carry the lamp socket and wiring terminals.
